An efficient digital signature using self-certified public keys
Yuan Hua Zhou, Zhenfu Cao, Rongxing Lu · 2004
In this paper, we first analyse the notion of self-certified public keys, which was first introduced by Girault [5], and then we extend it. After that, we will adopt the extended concept to propose a new signature scheme. The proposed scheme has a property that the signer's public key can simultaneously be authenticated in verifying the signature. Compared to earlier self-certified signature schemes, our scheme is more efficient and provable secure.
